Abstract

Background: The year 2020 witnessed the rapid spread of covid-19 pandemic in Iraq and in almost all the countries in the world. This spread has created a serious health crises and a public health emergency in Iraq and throughout the world. Throughout the world, healthcare systems have been negatively influenced by the pandemic and experienced unexpected changes. We have previously provided several descriptions of the Iraq health care system from its evolution. However, little is known about the health care system in Iraq during the first year of the coves pandemic. The aim of this paper is provide a description of the healthcare system in Iraq during the year 2020, the first year of covid-19 global pandemic.

Materials and methods: The available unpublished and published data about the Iraqi healthcare system during the first year of covid-19 pandemic, the year 2020 were examined. The data included more than 100 relevant unpublished and published information documents including journal articles, books, official reports of the Iraqi Ministry of Planning and Iraqi Ministry of Health. In addition, relevant useful data available at internet web sites were also reviewed. The available relevant data were classified into categories including; demographic data relevant to healthcare, Data related to covid-19 disease in Iraq,  data related to the organizational structure of the healthcare system, data related to national healthcare policies including national healthcare mission, vision, strategic goals and plans, data related to healthcare system financing,  data about healthcare services delivery, data about the workforce in the Iraq healthcare system, data related to child health and maternal, data about notifiable infectious disease, data about chronic disorders and the main causes of  morbidity and mortality, and data about medical education and healthcare education. Many relevant healthcare data for three provinces (The Kurdish provinces in the north of Iraq) of the eighteen provinces in Iraq were not available in English or Arabic.

Results: The population of Iraq in 2020 was estimated at 40.150.174 (20.284.823 males and 19.865.351 females). During the year 2020, 595291 cases of covid-19 disease were registered by the Iraqi Ministry of Health. 12813 (2.15%) patients died and 537841 (90.3%) patients experienced recovery. The organizational structure of the Iraq health system, the backbone of the Iraq healthcare system witnessed no important change from the description before covid-19 global pandemic in 2019. 

The declared mission and vision of the Iraqi Ministry of Health for the year 2020 were the same mission and vision of the Iraqi Ministry of Health that were declared in 2018. In 2020, the Iraqi Ministry of Health declared a strategic plan which included a vision and mission statements for the health information system. The first year of covid-19 pandemic in Iraq was not associated with an important increase in the number of primary healthcare centers. However, there was little increase in the number of governmental hospitals. Surprisingly, the bed occupancy rate of governmental hospitals during the first year of the pandemic was lower than the bed occupancy rate during the two years before the pandemic. The total number of hospitalized patients in 2020 was lower than the previous four years, but the mortality rate per 1000 hospitalized patients was significantly higher in 2020 than the previous four years.

Conclusion: Covid-19 disease in Iraq was associated with a significant mortality during the year 2020. It actually changed the previously reported national mortality pattern as covid-19 has become the second most common cause of death in Iraq. Contradictory, to the general belief that mortality associated with covid-19 disease was generally restricted to the older age groups, 117 children under the age of ten years died because of covid-19 disease in 2020. This number of childhood deaths suggests the need to consider vaccination of the younger age groups and to perform the relevant research. Covid-19 disease has emerged as a new notifiable infectious disease in Iraq and throughout the world; therefore, it changed the pattern of notifiable infectious diseases in Iraq.

Introduction

There are four genera of coronaviruses including alpha-coronaviruses, beta-coronaviruses, gamma-coronaviruses, and delta -coronaviruses. Alpha and beta-coronavirus can infect mammals, while gamma-coronavirus and delta-coronavirus generally infect birds. Four coronaviruses are known to cause mild upper respiratory infection in humans of all ages including infants. 

The transmission of coronaviruses from animals (birds) to causes respiratory illness has been reported as early as 1969 by Kapikian et al. Community-wide outbreak associated with 229E-like coronavirus has be reported as early as 1970 by Cavallaro and Monto. Until December, 2020, two beta-coronaviruses (SARS coronaviruses and MERS-coronaviruses were known to cause severe, potentially fatal pneumonia-like illness [1-6].

Errors in the replication of viral genomic RNA of zoonotic coronaviruses led to the emergence of genetically related diverse quasi-species, while the transmission of some of them to a new host species led to the emergence of human severe acute respiratory syndrome coronavirus (SARS-CoV) and Middle East respiratory syndrome coronavirus (MERS-CoV). SARS-CoV emerged for the first time in Guangdong China in 2002 spread rapidly to many other counties causing more than 8000 cases with about10% mortality. In 2012, it was thought that MERS-CoV was transmitted to humans from bats through an intermediate camel host leading to 1700 cases in 27 countries with about 40% mortality [1-4].

Increasing number of cases of severe potentially fatal pneumonia caused by a new β-coronavirus was reported from Wuhan China in December 2019, and human-to-human transmission was confirmed early. On the 12th of January, 2020 the World Health Organization (WHO) officially named the condition coronavirus disease 2019 (covid-19). The Coronavirus Study Group of the International Committee suggested naming the new coronavirus “SARS-CoV-2” [1-4]. 

The year 2020 witnessed the rapid spread of covid-19 pandemic in Iraq and in almost all the countries in the world. This spread has created a serious health crises and a public health emergency in Iraq and throughout the world. 

Throughout the world, healthcare systems have been negatively influenced by the pandemic and experienced unexpected changes. 

We have previously provided several descriptions of the Iraq health care system from its evolution. However, little is known about the health care system in Iraq during the first year of the coves pandemic.

The aim of this paper is provide a description of the healthcare system in Iraq during the year 2020, the first year of covid-19 global pandemic.

DEMOGRAPHIC DATA RELEVANT TO HEALTHCARE

The population of Iraq in 2020 was estimated at 40.150.174 (20.284.823 males and 19.865.351 females, with 102 males for each 100 females). 

40.5% of the population was under the age of fifteen years, and 5 Percentage above the age of 60 years. Figure-1 shows the age distribution of Iraq population during the year 2020. 69.8 % of the population was living in urban areas and 30.2% were of the living in rural areas.

Data Related To Covid-19 Disease In Iraq

During the year 2020, 595291 cases of covid-19 disease were registered by the local and national health authorities, 12813 (2.15%) patients died and 537841 (90.3%) patients experienced recovery. 256 patients who died from covid-19 disease were affiliated to the Iraqi Ministry of Health including 56 medical personnel and 133 health personnel.

The spread of covid-19 disease in Iraq was first recognized during February, 2020 with the report of the first confirmed cases of the infections on the 22nd of February in the province of Najaf. 

The first reported case in Iraq was an Iranian student of religion. The first case of covid-19 in the Kurdish region of Iraq in the North of the country was reported on the first of March, 2020. However, the first death from covid-19 disease in Iraq was reported from the province of Suleimaniya in the Kurdish region of Iraq. The patient was a 70-year-old man who was known to have chronic heart failure associated with asthmatic manifestations.

The second death from covid-19 diseases in Iraq was reported from the province of Baghdad, while the first recovery was reported on the 6th of March. 

On the 27th of March, 2020, all 19 Iraqi provinces have reported confirmed cases, and on the 7th of April, 28,414 tests have been performed with 1202 of them were positive. 

On the first of April, 2020, the total number of confirmed covid-19 disease cases in Iraq was 728. Early during June, the number of the reported cases exceeded 12,000, and the deaths exceeded 300. Table-1 shows the confirmed cases of covid-19 disease in the provinces of Iraq on the 7th of June 2020.

On the 28th of June, the Iraqi Medical association reported occurrence of 45402 cases of covid-19 diseases including 788 Iraqi doctors, and 1756 patients died and including 13 Iraqi doctors. 

People whom were considered to be healthy and possibly having good immunity like former football players and bodybuilding champions (Figure-2A) also died during the year 2020.

Table 1: The confirmed cases of covid-19 disease in Iraq in the provinces of Iraq the 7th of June 2020.
Figure 2A: Mohammed Al-Kaabi, an Iraqi bodybuilding champion who died because of covid-19 disease during the year 2020

The death of Ahmed Radhi (Figure-2B) , a former player of the Iraqi National football team during June 2020 was associated with public criticism for the Iraqi Minister of Health  during that time who was regarded as a non-technocrat minister as he was a military pharmacist and nor a real physician. Shortly after the death of Ahmed Radhi, Haider Al-Mulla , a politician asked the prime minister to appoint a real Minister of Health.

It is worth mentioning that Hassan Mohammed Abbas, the minister of health during that time was forced to resign during the year 2021 following the occurrence of a huge fire in Ibin Al-Khateeb Hospital in Baghdad and killed many patients.

In Iraq, a high covid-19 disease ministerial committee was established by the Iraqi Ministry of health to lead the efforts to control. The committee designed an official protocol (Figure-3) for the treatment of the disease and distributed it to hospitals. 

Lopinavir/ritonavir + ribavirin combination was at the top of the suggested therapies to be used in the treatment of covid-19 disease, and that was excellent from the evidence-based medicine point of view. However, the suggested treatment was not available at all in the country. The second suggested treatment was plasma therapy which was impossible to offer to any patient needs treatment supposing that it is an acceptable therapeutic option.

Figure 3: The official protocol designed by the higher ministerial committee for the treatment of covid-19 disease

During the year 2020, 182607 cases of covid-19 disease were registered in Baghdad accounting for 31% of the total cases of the disease in Iraq. Table-2 shows the number of covid-19 disease cases in the Iraqi provinces during the year 2020 and their outcomes of death or recovery. 

7680 (1.4%) of the covid-19 disease in Iraq during the year 2020 were under the age of ten years, and therefore this age group was the least to be affected with covid-19 disease in this study. 133176 (23.9%) of the covid-19 disease in Iraq during the year 2020 aged between 

30 and 39 years, and therefore this age group was the most affected with covid-19.

 Figure-4 shows the age distribution of covid-19 patients during the year 2020. Table-3 shows the percentage of the recovered patients in various age groups. 

Table 2: The number of covid-19 cases in the Iraqi provinces during the year 2020.
Figure 4: The age distribution of covid-19 patients during the year 2012.
Table 3: The percentage of the recovered patients in various age groups.

During the year 2020, 173928 individuals died in Iraq including 12813 deaths because of covid-19 disease which accounted for 7.36 % of the total deaths in Iraq during the year 2020.  Covid-19 resulted in a death rate of 33/ 100000 population in Iraq during the year 2020.

117 (0.9%) of the patients who died because of covid-19 disease in Iraq during the year 2020 were under the age of ten years, and therefore patients in this age group are the least likely to die from covid-19 disease. 2418 (18.9%) of the patients who died because of covid-19 disease  aged 50 to 59 years. 

Therefore, according to this study, patients in this age group are the most likely to die from covid-19 disease. Figure-5A shows the number of deaths in various age groups, and figure-5B shows the percentage of deaths in various age groups.

Figure 5A: The number of deaths in various age groups
Figure 5B: The percentage of deaths in various age groups

Covid-19 disease was the second most common cause of death in Iraq accounting for 7.36% of all deaths in 2020. Covid-19 disease was also the second most common cause of death in males, but it was the sixth most common cause of death in females. However, covid-19 disease was the third most common direct cause of maternal death.

Covid-19 disease was the sixth most common cause of hospitalization of patients aged 20 to 24 years in Iraq except the Kurdish provinces in the North of Iraq during the year 2020 accounting for 0.95 %.                                                                                                          

Data Related to The Organizational Structure of The Healthcare System

The organizational structure of the Iraq health system, the backbone of the Iraq healthcare system witnessed no important change from the description  before covid-19 global pandemic in 2019 [7,8,9,10].

Discussion

Like most of the world’s health systems, in Iraq, the most important factor affected the healthcare system in Iraq in 2020 was the spread of covid-19 disease. The covid-19 pandemic changed the mortality pattern in Iraq as covid-19 disease emerged as the second most common cause of death. Table -15 shows the most common causes of death in Iraq in 2018 and 2019.

Table 15: The most common causes of death in Iraq in 2018 and 2019.

Covid-19 disease has emerged as a new notifiable infectious disease in Iraq and throughout the world; therefore, it changed the pattern of notifiable infectious diseases in Iraq.

A total of 718393 cases of notifiable infectious disease including covid-19 disease were registered in Iraq in 2020. Figure-8 shows the percentage of the main notifiable infectious diseases including covid-19 registered in Iraq in 2020.

The first year of covid-19 pandemic in Iraq was not associated with an important increase in the number of primary healthcare centers (Figure-9). However, there was little increase in the number of governmental hospitals (Figure-10). 

Figure 8: The percentage of the main notifiable infectious diseases including covid-19 registered in Iraq in 2020.

Surprisingly, the bed occupancy rate of governmental hospitals during the first year of the pandemic was lower than the bed occupancy rate during the two years before the pandemic (Figure-11).

Figure 9: The number of primary healthcare centers in 2013, 2018, 2019, and 2020.
Figure-10: The number of governmental hospitals in 2013, 2018, 2019, and 2020
Figure 11: The bed occupancy rate (%) of governmental hospitals in 2017, 2018, 2019, and 2020.

The total number of hospitalized patients in 2020 was lower than the previous four years (Figure-12), but the mortality rate per 1000 hospitalized patients was significantly higher in 2020 than the previous four years (Figure-13).

On the first of June 2021, 1,201,352 cases of covid-19 disease were reported by the Iraqi Ministry of Health, and 16375 patients died because of the disease. During, the first week of June, 2021, the death of three Iraqi patients having covid-19 disease complicated by mucormycosis was reported [11, 12, 13]. We are recommending adding mucormycosis to the list of notifiable infectious diseases,

Figure 13: The mortality rate per 1000 hospitalized patients in 2016, 2017, 2018, 2019, 2020.

 

Conclusion

Covid-19 disease in Iraq was associated with a significant mortality during the year 2020. It actually changed the previously reported national mortality pattern as covid-19 disease has become the second most common cause of death in Iraq. Contradictory, to the general belief that mortality associated with covid-19 was generally restricted to the older age groups, 117 children under the age of ten years died because of covid-19 disease. This number of childhood deaths suggests the need to consider vaccination of the younger age groups and to perform the relevant research.  Covid-19 disease has emerged as a new notifiable infectious disease in Iraq and throughout the world; therefore, it changed the pattern of notifiable infectious diseases in Iraq.

I am very pleased to serve as EBM of the journal, I hope many years of my experience in stem cells can help the journal from one way or another. As we know, stem cells hold great potential for regenerative medicine, which are mostly used to promote the repair response of diseased, dysfunctional or injured tissue using stem cells or their derivatives. I think Stem Cell Research and Therapeutics International is a great platform to publish and share the understanding towards the biology and translational or clinical application of stem cells.
